While developing and deploying software continue to be more broadly accessible, so is the problem caused by these systems' security not being considered enough by their developers and maintainers. We propose to address this developer-centred security issue with serious games (games for which entertainment is not the main purpose) as a means to motivate developers to consider security threats when developing. We have developed a serious game around secure and non-secure programming exercises to investigate if serious gamification helps to improve attitudes or ability with secure programming. We detail the design choices of the game and how it relates to the programming tasks. In particular we present the design choices we made with the intention to replicate a prior study and discuss the tension that arose between replication and intervention. We discuss the results of a pilot study we conducted and present the steps we plan to take going forward into larger studies.
